This invention relates to improvements in plumbing fixtures, aparticular purpose being to provide a floor drain so designed thatseepage will effectively be disposed of to T which end it consists ofthe constructions,

combinations and arrangements herein described and claimed.

'An object of the invention is to provide the body of a drain with,seepage channels which at one end have communication with the drain pipeand at the other endare' open to points outside of certain fittings thatvare used in the installation of the drain, so that water percolatingaroundysuch fittings Will find its way into the drain pipe.

A further and important object of the invention is to employ a clamp forthe double purposes of securing a water-proofing material such astarredpaper to the flange of the strainer body and guarding the seepagechannels in said body so that the latter cannot become obstructed whenthe drain is embedded in a plastic mass.

Other objects and advantages will appear which Figure 1 is a sideelevation of the improved floor drain, a portion of a drain pipe'beinshown connected therewith,

Figure 2 is a vertical section showing the drain installed in a floor,

Figure 3 is a plan view of the drain, Figure 4 is a cross section takenon the As indicated in one of the brief statements of the objects of theinvention, the principle of the latter is to allow for the seepage ofmoisture into a drain pipe from points outside of certain fittings whichare used in the installation of the drain. This purpose may beaccomplished in drains other than those used in floors, and theembodiment of the,

outstanding features in a floor drain is not to be regarded as alimitation.

In the drawings the body l is internally threaded at 2 at the lower endto receive the drain pipe 3. The end of the drain pipe abuts an annularshoulder 4 which prevents the closure of one or more seepage channels 5which have outlets 6 in the circumferential face of the shoulder. Werethe shoulder not provided there would be the grave possibil ity of the'body l being screwed down so far ppon the drain pipe'as to obstruct theout etsfip The channels 5 are formed in a second internally threadedbore 7, this at the other, side ofthe shoulder- 4, into'which bore thenipple 8 of an inlet or 'receiver'9 is screwed until it too abuts theannular shoulder 4.,

that far. Varying thicknesses of the plastic floor10 willdetermine theextent: towhich,

thenipple 8 is screwed-imbut the minimum I floor thickness would be thatat which the nipple" is screwed down to the limit. r It's observed thatthe external threads on the nipple 8 extend throughout its length. I

This is -to"r'e'ceive the internallythreaded wrench head 11 of the'clampl2. The clamp is preferably round but not necessarily so.

The'peripheral edge is curled down at 13 thus defining a seepage chamber14 when the clamp is screwed down upon the flange 15 of'the drainbody 1. Qpenings 16 intl1e-"curled edge 13"ad1nit any moisture to thechamber 14 that may percolate either through the floor 10' or around thefittings of the drain to a sheet 17 5 The nipple 8 isnot necessarilyscrewed down of'water-proofing material. The'peripheral edge'ofthefiange 15 is curledupat 18, 'giving thefiangethe appearance of a"dish. The" ,water-proofing material, whether that be.

tarred paper, sheet lead or the like, laps into the dish far enough'topermit the clamp 12 to befscrewed thereupon to make a tight connection.v I g Inasmuch as tlie seepage channels 5 extend up to the "top'surfaceof the flange 15, it fol lows that they communicate with the chamber.14. 3 Any moisturektliatmay percolate through the floor to the sheet-ofwater-proofing '17 will ultima'telyfind': its Way into the dish18fchamber 14' and thechannels 5 whenceit will run off into the drainpipe'3.

A slotted cover 19 is secured to the receiver 9. This Ii'ifiush with"the floor 10. Upon installing the drain, the body 1 is fixedin positionuponthe' drain pipe and the water back up. under it.

proofing sheet 17 laid over all adjoining supporting structure of thefloor and made to lap over the flange 15. The nipple 8 with its clamp'12 is screwed in place in'the bore 7.

The clamp 12 is then screwed down until it firmly binds against thesheet 17 It is an outstanding purposeof the inventionto provide andutilize the clamp12 for; the securing of the sheet 17. This must befixed in place around the drain, and it must be clamped down so hardthat water cannotl The second major pur- I pose of the clamp 12 is toguard the seepage channels5.

These must not be obstructed. The plastic'material of whichthe floor iseither composed or which enters the construction of thefioor willbepacked around the drain fittings as illustrated in Fig. 2. The dishedclamp 12 will prevent the packing from' reaching the channels 5 and willestablish the V in outside of the drain fittings.

chamber 14 intowhich the moisture will seep prior to entering thechannels.

Fundamentally, therefore, the improved drain provides a through passagefor the drain water, the former being represented bythe nipple 8 anddrain pipe 3, which pas sa c has one or more external channels, thatafiord communication thereof from points ]I claim 2- e 1.
